Re: [gpsd-users] Problem with gpsd blocking device while it doesn't send NMEA messages

[Larry Boyd]

The problem is that that unit needs you to send a start command to it to turn it on and start it up.

You can either use wvdial like this;

Or you can use gpsd device-hook like this;

Not a gpsd problem if it happens before you use gpsd.

Also, I do not see how you can 'cat' from a device that is already opened
by your picocom.  The kernel should prevent that.

One big important detail: what GPS are you using?  Got a pointer to its
documentation?

Which gpsd are you using?  Did you build it yourself?  Does it hae the
GPS driver you need?

To eliminate some variables, what happens if you try just:
        gpsmon /dev/ttyAMA2
